Key Concepts

Continuity

Continuity in a function means that the function has no breaks, jumps, or holes at any point in its domain. A function is continuous at a point if the limit at that point exists and is equal to the function's value. Ensuring continuity often involves defining the function appropriately at points where it is originally not defined.

Limit

The limit of a function as the variable approaches a particular value is a fundamental concept used to understand the behavior of the function near that point. In cases where the function is not defined at a point, such as the exceptional point, the limit helps in determining the value that the function can be assigned to restore continuity.

Removable Discontinuity

A removable discontinuity occurs when a function is not defined at a point, or its value does not match the limit at that point, despite the limit existing. By redefining the function's value at this point to equal the limit, the discontinuity is 'removed', making the function continuous.

Algebraic Simplification

Algebraic simplification involves manipulating expressions to cancel common factors between the numerator and denominator in a rational function. This technique is often used to identify and eliminate an indeterminate form, such as 0/0, which is crucial in finding the limit at points where the function is not initially defined.
